Scientists identify genetic components of left-handedness

Scientists identify genetic components of left-handedness

For the first time, scientists have pinpointed regions of human DNA that closely relate to whether people are right- or left-handed. They also linked these regions to language-related features in the brain. New research pinpoints the genes associated with left-handedness. Previously, scientists knew that genes were responsible for around 25% of handedness. However, before the […]

Using the body clock to make drugs more effective

Using the body clock to make drugs more effective

Researchers created a database for the daily circadian rhythms of genetic activity. The findings may help physicians time the delivery of drugs in accordance with a person’s body clock, boosting treatment for cardiovascular disease and other conditions. Our body clock can influence how effective drugs are — especially for treating cardiovascular problems. Our circadian rhythm, […]

When you’re going through a tough time, some people seem to know almost instinctively what you need, while others, although well-intended, may not be able to offer the emotional support you’re hoping for. Is this because the ability to empathize is innate, or down to our genetic inheritance? A new study investigates. Our ability to […]
